Be it known that .I. HERMANN ZEGLIN, a subject ofthe King of Prnssia, German Em peror. and resident of 39 Stralauerst-rasse, Berlin. Germany. have invented new and Inproved Means for a New and Inproved Corner-Bead I `astening. of which the following is a speeification.

This invention relates to means for fastening metal corner beadin to masonry. Sneh beadings are employee?,` for instance, on 'the edges ot' steps to protect the said edges from being too rapidly worn away.

The object of the present invention is to provide a convenient and simple method for fixing the dowel pins to the said beadings.

Itis old to provide the beadngs with a groove and to fix the dowel pins at a suitable pont in the groove, where the said pins have ?and improved means for to be driven into the wall.

The present invention relates to a simple fixing the said dowel pins at any desired point in the length of the groove without the neeessity of employing any hanmering action.

'l`o this end the improved fastening device consists of a dowel pin-having a head set at an angle to the provided with a slot key which on rotation widens the slotand thereby eanses the head to grip tightly in the groove ot the `eorner heading.

The aeconparving drawings il'lustra te the present invention as appled to a" protecting eorner piece.

Fignre 1 is an illustration of the protect: ing corner piece and' dowel pin showing the method of fastening the dowel pin in the groove of the corner piece. Fig. 2 is a detaehed View of the tool which I may employ for widening the head of the dowel pin in the groove. F ig. 3 shows the proteeting corner piece in position on, a piece of masory.

adapted to receive a 'a slot (i.

said pin. said head being' In carrying the invention into etfeet ae` cording to the form shown the angle piece 1 is provided on the sides ot' the angles with projeetions 2 which form shoulders 3. The shonlders 3. as can be seen in Fig. 1. forn an underent groove on the inner sdes of the angle. Into this groove there passes the. head 5 of a dowel pin 4. The head 5 is conveniently bent substantially at. right angles to the point 4 and 'is provided with 'hen the dowel pin has been moved along the nndercnt groove in the angle piece 1 till it is at the point desired the key 7 isinserted in the slot 6 and by rotatng the said key the slot (i is widened so that the head I is janmed in the groove behind the shonlders 3. The angle piece so arranged is then fixed to the masonry 8 in the nsnal nanner.

I claim i 1. The conbination With a metal eorner heading', having a longitndinal groove there in. of a dowel pin having a head piece set at an angle thei-eto, said head arranged to fit and to slide in said. longitndinal groove in the heading and having a slotadapted to `be widened to cause said head to be held tightly atany suitable place within said groove. 4

9. In eonbnation -with an angle iron, underet on its two inner slides tofomi a groove, a dowel pin having a head thereon bentsbstantially at right angles tlereto, said head being provided with an elongated slotadapted to be wdned to cause said head to jani tightly within said nndercutgroove` snbstantially as deseI'ibedL-L` In witness whereof I have hereunto set my hand n the presence of two witnesses.
